100% private · your audio file is processed locally and is never sent to our server.

How it works

  1. Click the drop zone or drag your M4A file in.
  2. Your browser decodes the audio locally using the Web Audio API — no upload happens.
  3. Click convert; the MP3 file is generated on your device in a few seconds.
  4. Download the result directly. Nothing was ever sent to a server, so there's nothing to delete.
